One of the exciting features of upcoming Swift 4 is Multi-Line String Literals. I often need a quick way to create a prototype app with JSON data. Usually, I need to save data to local JSON file and then read from file or use network layer. That takes time.
Previously it wasn’t possible to use such strings like string literals.
In Swift 4 you can just copy/past it like this:
""" JSON/XML/OTHERS COMPLEX STRINGS """
